Anonymous users2024-01-23The dual control switch is available with wiring markings N, N1 and N2. A switch N is connected to the power live wire, B switch N is connected to the lamp, two switches N1 and N2 wires are connected, A N1 is connected to B N1 or N2, A N2 is connected to B N1 or N2, and the other end of the lamp is connected to the zero wire. Do you see?
It's still two wires, one switch next to the door and one at the head of the bed. That is, choose one of the two lines and connect two switches according to the distance you need.

If the ceiling lamp is turned off and measured with a pen, there should be two reasons: one is that the switch control back is the zero line, there is no answer to control the live wire, the shutdown is the zero line, the live wire is still there, if so, it is dangerous, it should be adjusted, and the switch controls the live wire; Another reason is that there is a rectifier source or a segmented controller in some lamps, where there is an electrolytic capacitor, just after the switch is turned off, the electricity on the capacitor has not been discharged, so it can be measured, if so, wait until a long time, this voltage is gone.
